Data Interchange Challenges
• Between information management system and– instruments (instrument interfaces)– other internal- and external systems (system interfaces)
• Lack of a common and open definition for the instrumentinterface
• Lack of a common conceptual data interchange frameworkbetween instruments and information systems
• => Since no universal solutions exist, all data interfacesneed application-specific consideration and have to beprogrammed
12
12
Technical and Conceptual Challenges
• Compatibility of instrument operating system withthe IT infrastructure to facilitate the connection to the Blood Service network
• Technical compliance level with the ASTM high-and low level protocols
• A variable level of technical manuals and supportavailable
• Availability of one- and bidirectionalcommunication
• Selection between batch- or query mode• Selection of relevant data to be transferred• Human checkpoint of results• Alternative system in case of a breakdown• Information security (closed vs. open system)• Risk assessment - interfaces are critical elements
within a GMP critical system – validation!

13
Communication Related Challenges
• Co-operation and information exchange between the partiesinvolved: Blood Service, the instrument (automation system) supplier, the LIMS supplier, the IT service provider(s), the external client and their IT service provider(s)
• A BS expert and the IT expert do not necessarily speak the samelanguage. Yet a common understanding of the functionalitiesneeded is required
• How to understand the variable technical solutions suggestedand the consequences of the choices made?
• Functional specification, design specification, testing of the pilotversions, correction of errors and possible modification of the specifications, retesting… an iterative process until the interfaceoperates as specified
14
14
As a consequence
• The interfacing takes time and extra effort• The amount of programming and the amount of testing
needed varies depending on – Instrument (automation system) interface type– Availability of detailed technical information– Availability of support from the instrument or system supplier– Number of parties involved– Complexity of the user requirements set for a particular
interface– …– Special Experts available for the job
=> Extra costs!

Standardization and Data Interchange Successes
• "…global, platform-independent data standards that enable information system interoperability to improve medical research and related areas of healthcare." Clinical Data Interchange … www.cdisc.org
• HL7 "Level Seven" refers to the highest level of the International Organization for Standardization (ISO) communications model for Open Systems Interconnection (OSI) - the application level. The application level addresses definition of the data to be exchanged, the timing of the interchange, and the communication of certain errors to the application. The seventh level supports such functions as security checks, participant identification, availability checks, exchange mechanism negotiations and, most importantly, data exchange structuring. The HL7 Version 2 Messaging Standard — Application Protocol for Electronic Data Exchange in HealthcareEnvironments — is considered to be the workhorse of data exchange in healthcare and is the most widely implemented standard for healthcare information in the world." www.hl7.org

Standardization and the Data Interchangein Transfusion Medicine Activities
• "Standard Specification for Transferring InformationBetween Blood Bank Equipment and InformationManagement Systems" ICCBBA draft standard from 1998 www.iccbba.org on the basis of ASTM E 1394/1381…
• ASTM E 1394/1381 withdrawn in year 2002 and replacedby ANSI/NCCLS standards, such as Laboratory Automation: Communication with Automated Clinical LaboratorySystems, Instruments, Devices, and Information Systems; Approved Standard; NCCLS Document AUTO3-A, ISBN 1-56238-428-7 www.clsi.org
17

Task Force on Automated SystemInterface
• Established in 2006 to develop a standard specification for transferring information between equipment and informationmanagement systems within transfusion medicine activities
• Timeframe: the standard suggestion should be presented for consideration by ISBT in 2009/10
• Ongoing activities– Building networks: Apheresis (K. Bierbaum), Production (P. Potstra),
Testing Instruments (NN) – Compiling a list of instruments and equipment (B. Lupo)– Comparison of the ANSI/NCCLS standard AUTO3-A with the draft
ICCBBA standard from 1998 … and reviewing of data interchange standards such as ASTM E 1238, 1381, 1394, 1467, 1578, 1639; ANSI X3.4, ISO 8859-1, ISO/IEC 10646, 7064; plus CLSI, HL7, CEN TC 250, ISO TC215, IEEE 1073 protocols 18

Conclusion
• Risk assessment – interfaces are critical within a GMP critical system (product quality, patient safety and information security)
• Regulations apply – validation!• Challenges and extra costs arise due to a lack of a common
and open definition for the instrument interface, and a lackof a common conceptual framework for data interchange
• Standardization is a need recognized by the end users and suppliers within the transfusion medicine activities
• ISBT launced a new Automated System Interface TaskForce in 2006 to establish a standard specification
• The timeframe required will be about three years (ISBT 2009/10)

Interfacing your Automated Instrument
Terry Downs MT(ASCP)SBBSupervisor, Blood BankUniversity of Michigan Health [email protected]
What is an Interface?
Automatic, electronic connection between an analyzer and a computer for exchanging information2 or more software applications are linked together and communicate as oneDifferent protocols available
Flow of data
Serves as means of communication between the lab system and instrumentInterface translates tests and accession numbers into a language the instrument can understand (downloading)Test results translated into a language the LIS can understand (uploading)
Unidirectional Interface
Samples Results Reports
Instrument performs test and sends results to interface/LIS
LIS
Bidirectional Interface
SamplesResults

Reasons to Interface
Safer FasterFuture stateAutoverification
Planning for Interfaces
Trend is for bi-directional interfaces particularly random access testingCost to develop interfaceOperation of interfacesIntegration with other LIS functionsPhysical layout-cable length, hardwareVendor support
Planning for Interfaces
What cables are needed?What sockets are on instrument and LIS for connection?What is the format of data from instrument?Can the LIS receive it in that format?Are there symbols the instrument uses that LIS cannot use?Is middleware needed to translate?

21 - Full Time Employees in the Blood Bank5.5 – Full Time Employees in the Blood Donor Center
Statistics:
• 705 Bed Hospital
• 34,000 Type and Screens
• 25,000 Crossmatches
• 15,000 Red Cell Transfusions
• 8,000 Fresh Frozen Plasma Transfusions
• 6,000 Platelet Transfusions
• 1,000 Cryoprecipitate Transfusions
• 6,500 Whole Blood Collections
• 600 Trima Apheresis Collections
• Transmissible Disease Testing for donors and patients
Problems that we faced:
► Staffing► Clerical Errors► Technical Errors► Standardization of procedures
2
Our solution was…automation AABB Standard 3.1
• AABB Standards, 24th Edition states“The blood bank or transfusion service shall have a process to define the selection criteria for equipment.”
Our problem was…how to pick the best instrument for our laboratory So, we sat down and brainstormed… What
do we want in an instrument???
Qualities we sought in an automated blood type and screen analyzer:
• Ease of use
• Reagent quality control can be recorded and is required at 24 hour interval
• Turnaround time for results is within an hour
• STAT capability
• Large batch size capability
Qualities we sought in an automated blood type and screen analyzer (continued…)
• Patient testing (2-3 cell antibody screen) and donor testing (pool antibody screen) can be accomplished
• Each step of patient and donor testing is captured, together with date, time and electronic signature of staff performing testing/task.
3
•Reports can be generated that assist in statistical analysis of tests performed, (i.e.: # of tests done per year, # of NTD’s (no type determined), # of positive antibody screens, # of aborted runs, etc)
•Archiving of data is accurate, simple and quick.
•The system is ISBT-capable.
•Instrument interfaces exist for HCLL computer system.
•Security is guaranteed with user access and password codes.
•Users may be granted different levels of access.
•Aborted runs are printed for ease in review and tracking
•Backup system exists in the event of system downtime.
•Downtime is at a minimum and technical service visits are within 24 hours of phone call.
We devised a series of questions to help us with our decision. For example:
Which other sites are using the equipment?
Could we schedule a visit to a current site with a similar workload?
How many technical support specialists does the company have available in the region?
Do they offer 24/7 telephone support and field support?
Is there a national users group and how often do they meet?
What costs are included in the purchase/reagent rental? For example:
Maintenance costsInterfacesUninterrupted Power Supply (UPS)QC related supplemental equipment
-scale-standard weights
Decontamination supplies
What are the specimen requirements?
What is the turnaround time?
What are the space requirements?
Are there special plumbing requirements, i.e.: water supply, DI water, waste receptacles.
What are the electrical requirements?
What is the largest batch size that can be run?
Are the turnaround times different depending on batch size?
What is the NTD rate (no type determined)?
What is your rate for false positive antibody screens?
What reports are available?
Describe how stats are processed. Is there a stat interrupt?
4
What disposables are required and reagents are required?
What is their expiration date once opened?
How are plates run-i.e.: strips or full plates?
What is your policy for aborted or failed runs?
What is the downtime associated with daily QC, backups and maintenance?
Will maintenance requirements be kept track of by the instrument?
Daily, weekly, monthly, annually?
What are some examples of common troubleshooting problems?
How easily are the mechanical parts accessed?
Are there any space requirements for access to the instrument?
What computer interfaces are available? Are they bidirectional? Are they HL7?
How are results verified before accepted into computer system?
Does your system have anti-virus software?
What kind of training is provided by your company? How many staff is trained?
What is included if training is off-site (ie: hotel, transportation)?
How are software upgrades done? What is the downtime, if any?
Does your company need remote access to the instrument?
Have any parts been upgraded for the instrument?
Describe the levels of security for the instrument.
Will vendor’s technical support be on-site for go-live?
Depending on how many instruments you evaluate, create a spreadsheet and for each item assign a point system.
An unfavorable response is given a “0”.A response you can live with is given a “1”The most favorable response is given a “2”For example:
253Total Score:121
What is the NTD rate (no type determined)
021What is the turnaround time?111What is the overall cost?
Instrument C
Instrument B
Instrument AQuestion
Our choice was…..

Once your entire evaluation is done, present it to your administration and say a prayer ….
Soon enough you’ll have your new instrument in place and ready for the next frontier of implementation……..

Validation and Correlation of Blood Bank Analyzers
Presented by:Leana Serrano-Rahman MPH,
(MT)ASCP, (CQA) ASQMontefiore Medical Center
Bronx, NY
Montefiore Medical CenterTwo campuses -1,122 bedsOne Donor SuitePerforms approximately 9K TS/monthlyTransfuses approximately 25,000 red cellsTwo analyzers at each campusBoth campuses perform PEG tube testing
Validation? Correlation?
Let’s start with the simple definition…
Validation
Documented evidence that a specific process will consistently produce a specified productThe product meets the predetermined specifications and quality attributesDocument that the outcome of the process occurs “as expected”
Validation
Blood Bank software validation uses the same methodologies utilized for the validation of a Blood Bank analyzer
Correlation of Blood Bank Analyzers
NYS QA Std 15 states that a lab that performs the same test by different methods or instruments, or performs the same test at multiple sites shall have a system in place that evaluates and defines the relationship between test results at least 2 times a year.
2
Validation ? Correlation?Where do I go from here?I want a quality product AND I also want to….
Validation ? Correlation?…satisfy the regulatory agencies!
One of my favorite expressions…
During any type of validation, one of my favorite expressions is…”Just, kill me, kill me now!”
Validation Guidelines
Develop a validation plan/protocolIdentify the key players (who signs off on plan, summary, etc.)Execute validation planAnalysis of data collectedWrite a validation summary
Validation Plan/Protocol
Purpose- ”Produce documented evidence with a high level of assurance that all parts related to the use of an automated system work correctly and consistently.”Responsible Individuals for Execution- QA Manager, Lead Tech etcSign off of plan? Blood Bank DirectorSign off into production?
Validation Plan/Protocol
Description of analyzerActivities to be conducted for validationProcedures on “how” validation is going to be conductedInstallation Qualification (vendor)-system is installed correctly
3
Validation Plan/ProtocolOperational Qualification (OQ) operating parameters are working appropriatelyPerformance Qualification (PQ) consistency of the computerized processTrainingTestingDiscrepancy Resolution
Ready to execute plan…
Relax…you’re almost there…
Execution of Validation
Super users were sent for trainingIQ, PQ, OQ were performed by the vendor. The vendor has a checklist that was reviewed by the Blood Bank ManagerPQ Vendor vs. End User?
Execution of Validation- I
Run known blood types and neg antibody screen. Cover all types.Run a grossly hemolyzed specimenRun a QNS specimenDepending on the error codes of your analyzer, run specimens that would error out. Cover the whole spectrum.
Save the print outs!!
Execution of Validation- II
Instrument Parallel TestingThis was used as a form of performance validationPerformed patient testing (TS) using both the analyzer and the current reference method.Sample Size 200 patient specimens
4
Execution of Validation- III
ABIDSmall sample sizeRule outs with double dose cells performed by PEG tubeCompared historical cases as well as active patient specimens
Execution of Validation- IV
Known antisera-ABIDSerial dilution of known antiseraTested PEG tube vs analyzerUsed Anti Fya, Anti Jka and anti S
Execution of Validation- VInterface ValidationVerified instrument output posted correctly in patient recordVerify any applicable interface reports
Validation Summary
Summarize findingsInterpretation of results Any resolutions/corrective action of unexpected resultsProduction releaseSign off by appropriate authority
Reminders…Record retentionInstrument will still need future validation when applicableFile training recordsStore all print outsOperational SOP before go liveProficiency test
If I could do it over…
Would have run more specimens-at least 500.Tested more invalids, QNS specimens etc.Justify difference in run sizeSpecificity? Sensitivity?
